SHOE COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF DELAWARE MACHINE FOR TREEING BOOTS AND SHOES Application filed August 7, 1925.

This invention relates to machines for treeing boots and shoes and while not limited thereto has been more particularly designed 'for use in connection with treeing machines of the general type disclosed in Patent No. 691,576 granted January 21, 1902, to Harrie A. Ballard, for machine for treeing boots or shoes and relatesmore specifically to the construction and mounting of the shoe-engaging tools by which they are better adapted to closely follow the contour of the shoe during the operation of the machine. A further feature of this invention relates to a construction by which treating o'f the tool is facilitated.

For a more complete understanding of this invention, together with further objects and advantageous details of construction, reference may be had to the accompanying drawings in which Figure 1 is a side elevation of a treeing machine embodying the subject matter of this invention.

Figures 13 and 14 are detail plans of the devices shown in Figures 8 and 9, respectively, looking in the directions of the arrows.

As shown more particularly in Figure l the machine comprises a base 1 having a standard 2 at one end on which is supported Vfor rotation in a horizontal plane, a turret 3, having radially extending treeing forms Serial No. 48,716.

4 on which may be carried the boots or shoes as at 5 to be treed. Adjacent to the opposite end of t-he base 1 is a standard 6 which supports the holding and operating devices for the treeing tools which operate on a shoe carried by one of the treeing forms 4 when this treeing form is swung into proper relation thereto.

The standard 6 has a vertical slideway 7 formed near its upper end on which is mounted a vertically traveling slide or carriage S on which are supported the forepart trceing or ironing tools 10. The lower portion of the standard 6 has a similar vertical slideway 12 carrying` a vertically movable slide 13 on which is mounted a horizontally slidable carriage 14. The slide 13 carries two series of treeing tools 15 and 16, the tool 15 engaging the quarter of the shoe and the tool 16, known as the rand tool, engaging the sid es olf the shoe adjacent. to the sole.

Between the slides 8 and 13 is positioned a cam bar 2O pivoted at 21 to a bar 19 adjustably fixed to the standard 6 at its lower end and its upper end pivoted at 22 to a similar bar 23 likewise adjustable horizontally relative to the standard 6 by which mounting of the cam bar its angular relation to the vertical may be adjusted. The rand tool 16 is provided with a guide roller 24 which rides against the forward cam face 25 of the cam 20 so that the tool is guided to engage the sides of the shoe and closely follow along the sole.

The carriage 14 carries tools 30 which engage the back portion of the shoe, the carriage being positioned closely adjacent to the standard 6 when the slide 18 is raised upwardly so that the tools first engage the back of the shoe adjacent to the sole, the carriage being then moved away from the standard 6 so that these tools are caused to wipe lengthwise along the back seam of the shoe.

The upper and lower slides may be moved in the same manner as described in the Ballard patent hereinbefore mentioned in which the lower slide is first caused to move upwardly to bring the quarter and rand tools into engagement with the shoe and to wipe the sides thereof upwardly and to bring the baul; tools into engagement w'th the bach seam portion of the shoe. As the lower slide then moves downwardly, the carriage 14 moves horizontally to wipe over the back seam portion of the shoe and the side tools move downwardly, the upper slide following down to bring the tools carried thereby into engagement with the toe portion of the shoe and following the side tools carried by the lower slide as it retracts. Both the upper and lower slices are then moved upwardly, retracting the toe tools and advancing the lower side tools,A while the back tools again pass toward the sole of the shoe.

The position of the toe tools, one of the rand tools, and the back tools during one stage of their travel over the shoe is indicated in Figure 2, the quarter tools being emitted for the salte of clearness.

The present invention relates more particularly to the construction and mounting of the various tools. Particularly where p the shanlrsare crooked it is necessary that the tools engaging this portion of the shoe should be permitted considerable motion so to be able to conform to the change in shoe contour as they pass on to, or away from this portion. in order thatV the tools may be able to follow this change in contour, they are constructed Y accordingto this invention in a manner to permit them a universal rocking movement on their supports, rand while in many cases it is not so essential that the quarter tools should be similarly mounted, it is often desirable that they should'be so mounted. It is also desir'- able that the toe engaging toolsV should also be permitted universal rocking movement in order that they may conform freely and automatically to the contour of the toe of the shoe. Various constructions by which these tools may be given this universal rocking movement are disclosed in Figures 8 to 140i' the drawings.

i ln Figure 8 a toe tool is illustrated and as shown therein this toe tool is provided with a ball shaped socket 40. rlhis socket may be formed by cutting. a slot 4l inwardly from one face of the tool illustrated in Figure 13, this slot having a rounded inner end, the open end portion of this slot being later filled in by Ymeans of a plug 42 having a coneaved inner end 43 for engagement with the ball end 44 of a supporting piece provided with a shank 45 Outwardly ofthe concaved portion 43 the inner endof the plug 42 is inclined as at 46 and there is a similar oppositely directed in elination 4'? at the base of the slot, these two surfaces defining a flaring opening through which the shank 45 extends. The tool support may he formed in various ways as shown for example in Figures 10, 11 and l2, in each case, however, being provided with a ball shaped end. The shank portion 45 may be formed cylindrical as shown in Figure 11, but preferably it is formed of polygonal cross section either of uniform dimensions through out its length as shown at 146 in Figure 10 or tapering as shown at 147 in Figure l2. Where the shank portion is formed of polygonal cross section the opening through which it passes in the tool, opposite sides of which are formed by the inclined faces 4S and 47, is also formed of the same polygonal cross section, so that while limited universal rocking of the tool on the support is permitted any substantial swiveling of the tool about the axis of the support is prevented. In this manner the tools are maintained in such relation to the supports that they are always in position to properly engage the shoe as the slides carrying them are movedinto operative position. lf free swiveling of the tool is permitted, the tools must be formed to properly engage the shoeJ at. my angle or the tools must be held in proper relation to engage the shoe by other means, as for example, by weighting the tools so that they always tend to maintain such a position that they properly initially engage the shoe. Further relative' motion between the tools in the shoe would then cause them to automatically assume the proper relations thereto as they pass over the changes in contour of the shoe.

is shown in Figures l() and ll each of the tool supports may be provided with an outwardly extending flange portion spaced from the ball end and sleeve portion 5l ef;- tending therefrom. This sleeve portion 5l may be fixed in a suitable bracket to which may be fixed the supporting rod 56 by which the tool may be carried on its slide, this being similar to the tool mounting of the Ballard patent hereinbefore mentioned. rthe hollow sleeve portion` 5l, however, provides for an additional function in that may be used to house the inner end of an electrical heating unit 6() as shown in Figure 8. Since these units may be extended closely adjacent to the y tools they are more effective in heating the@ tools than if they were further removed. lu some cases also it may be possible to estel d the heat unit receiving opening through the sleeve portion 5l andveven into thc ball head 44. Such a construction is illustrated in Figures 9 and i4 in which is shown as applied specili'callyto one of the rand tools 16. This rand tool 16 is shown as having a ball socket formed by cuttin in from one face of the tool as shown inlfigure 14 and filling the outer portion of this lcut by means of a plus 'Y l/V here the Shi'nl; portion is of suliici i large cross sectional area, as shown in Figure 9, the socket for the heating element may be readily extended into the ball head being shown therein by dotted lines at. 67'. ln this ligure also is disclosed a pair of oppositcly disposed ears 68 and G9 on the tool which limitthe extent of universal rocking movement and also prevent material swiveling movement about'the axis of the support-'by engaging on the flat faces of the shank portion fil 47. The tool support Ytor the rand tool is shown as lined in a bracket 80 having an eX- tension 81 to which the roller 24e may be journaled.

`With these mountings ot the tools as hereinbetore described, it is seen that they are permitted a limited universal rocking movement relative to their supports so that they may automatically conform to the contour ol' the shoe over which they are being moved7 but in the preferred form they are prevented from any material swiveling motion about the aXis oi the supports so that they are always held so faced that they will properly engage the shoe when first presented thereto.

'I` he tools for engaging the back of the shoe along the back seam being ol rigid material are also preferably mounted for limited universal tilting or rocking movement, a preferred construction being shown in Figures 3 to 6. Referring lirst to Figure 3 it will be seen that the carriage 14 has an upwardly eX- tending bracket 90 for pivotally supporting on the pins 91 the levers or arms 92. Fach et these levers has fixed at one end a spring 93 by which this end is rocked downwardly under yielding tension toward the carril e li. Preferably there are two series ot such levers arranged one above the other as shown in Figure 3 and means is provided for limiting the extent ot tilting movement or" these levers as produced by the springs 9S. For the upper group ot levers this means may consist ot set screws 95 extending through the upper ends of the standards 90, the lower ends of these screws being positioned slightly to the opposite side of the pivots 91 from the springs 93 so that the levers are rocked upwardly until they strike these set screws by these springs. The lower pair of levers may have'their limits ot motion determined by means ot studs 96 passing through the support 90 and having eccentric portions 9i' with which the upper edges o' the levers may contact, the. angular adjustment ol' these eccentric portions determining the amount ot' movement ot these levers. Each ot the levers carries at its outer end a support 98 for a tool, each of these supports having socket portions 99 for an electric heating unit 100, each support being seated in a perforation in the lever and lined therein by suitable means such as a set screw 101.

As shown in Figures 3, 4, 5, and 7 the back treeing tools are arranged in pairs, each tool ot each pair being carried by its individual lever 92. Each ot these tools comprises a block 105 into one side of which is cut a slot 106 opening through its rear face and having a spherical shaped inner end portion 107. The upper ball shaped head 108 of the tool supporty 98 may be passed into the upper portion of each of these slots and when in proper position therein a plug 110 having a concave inner face 111 mating the ball end may be placed in the outer end of the slot and be tixed therein as by a pin 112. Fach of the blocks 105 has a series ot tins 120 extending from one edge spaced apart to engage loosely between similar tins of the mating block ot the pair and at the fin portion each ot the blocks is recessed as at 121 so as to engage over the back seam portion of the shoe and somewl'iat around on to the side faces thereof.

As shown best in Figures 5 and 6 the sides of the socket portion formed by the side walls of the slot 10G are somewhat wider than the Shanks 115 ot' the support 98 so that a limited rocking movement ot the blocks 105 on their supports from and toward the matin y block of the pair is permitted while the ond Ylaces ot' the slots and of the plugs 11G and 11.7 llare very considerably thus permitting a. more extensive endwise rocking movement ot the blocks. As shown in Figure 7 the shanks oli the supports 9S may be oi polygonal cines section.

Vhen the lower slide 13 is raised upwardly the quarter and rand tools first engage the shoe and during their continued upward movement the blocks 105 press against the back portion of the shoe, the springs 93 yielding a's the carriage 14 continues its upward movement with the slide 13 and at a suitable time the slide 14 is then given its outward movement to cause the blocks 105 to be drawn away from the sole portion of the shoe so as to wipe over the back seam portion thereor". rllhe mounting of the blocks relative to each other and relative to their supports permits them to conform automatically to the changes in contour of the portion of the shoe engaged thereby during this motion.

It will thus be seen that the various tools are so mounted -as to permit them to conform closely to the considerable irregularities of contour of the shoe being operated upon and due also to the efficient manner of heating the tools vthey are enabled to tree the shoes in a highly efficient and expeditious manner.

Having thus described certain embodiments of this invention it should be evident to those skilled in the art that various changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.
